SBS (Exchange 2007) Out Of Office is not functioning externally. (It works internally)
Initially I checked that the out of office was enabled in Exchange, and it was. ("Allow external out-of-office messages and 2003 etc" and "allow automatic replies" and forwards on the format tab. This is the case on both the SBS transport and the default. )
I set up 'expert' level logging on MS Exchange for MSExchangeIS -> 9000 Private -> rules, MSExchangeMailboxAssistants -> OOF Assistant, -> OOF Library and -> Service
After adding the diagnostic logging a warning appeared in the application event log:
"The rule (1-RULENUMBER) with sequence number 50 is being ignored because it is disabled. The distinguished name of the owning mailbox is USERNAME. Database "First Storage Group\Mailbox Database"
Initially there was only one user and not the user who I was sending the test emails too. I presumed the users rule was corrupt and it was effecting all the other users rules.
I therefore tried using MFCMapi on a workstation to connect to the profile concerned and delete_hard_delete the IPM.Rule.Message entries for the user and that user hasn't appeared again in the event log....yet.
However as the minutes pass more warning events are being logged for other users. I tried deleting the rules for the next user but that user continued to have more warnings when I tested the out of office from an external address, so it didn't resolve the issue.
I have also just had an event warning for a user with sequence number 100. If that means anything?
I'm not sure where to go from here. Help appreciated.
